We designed the Endurance Compression Baselayer down to the last detail to help you perform your best in all the ways you train. We started with the fabric - a midweight, durable performance knit that can take a beating. It's moisture-wicking, quick-drying and stretches with every jump, lunge and squat. Our signature mesh Breathe Zones are strategically located where you sweat the most to allow for more airflow and ventilation during the most intensive workouts.

Then, we placed a media pocket in an optimal position to keep your phone high on your hip, locked down and out of the way to eliminate bouncing during runs and dynamic workouts (pocket fits iPhone 11, 11 Pro, XS, XR, X models). The high-stretch mesh mobility gusset allows the compression shorts to "disappear" - at full stride, you'll barely know they're there. We finished the compression shorts with chafe-free flatlock seams and a thicker no-roll waistband to provide you with performance, durability and comfort in any pursuit.

The Endurance Compression Baselayer fits true to size in the waist and have the same comfort enhancing features and waist size as our Standard Fit and Athletic Fit boxer briefs but with an extended 8" inseam that hits above the knee.

      Size fits me well

      Ordered a Medium based on the sizing guide and it fits great. This is the first time I've used a horizontal fly. I was skeptical for some reason and was surprised at how comfortable it is to use. The material itself is smooth and feels like it will last a while.
